Description

Improve fire safety and system reliability with the 2011 NFPA 85: Boiler and Combustion Systems Hazards Code. Updated for 2011, this comprehensive document applies to the full range of large boiler installations and pulverized fuel systems: * Large boilers, including atmospheric fluidized bed boilers with a minimum fuel input rating of 12.5 million Btu/hr (3.6 MW) * Stoker operations * Pulverized fuel systems * Fired or unfired steam generators used to recover heat from combustion turbines Major changes for 2011 include: * New definition and rules for a Combustion Turbine Purge Credit enabling designers and operators to establish and maintain a “purged” condition for heat recovery steam generators between restarts * Streamlined requirements for continuous trend display for single burner boilers * Revised boiler requirements for purging the boiler enclosure where no fans remain in service * Expanded guidance on burner management system design describes the types of signals and transmitters used to initiate safety alarms and interlocks and appropriate monitoring methods * Added guidance regarding flue gas analyzers installed in the flue gas stream Complete with a timesaving chapter on common requirements for all boilers, the 2011 NFPA 85 contains important provisions for boiler or combustion system designers, operators, and enforcers working with these systems.
